When Dalton finds out that he has a sister, he vows to track down his only kin, but his quest falters at the first hurdle. The orphanage where they lived has burned down and nobody remembers anything about the place and the children who were housed there.

Dalton is relieved when he learns that records still exist of their time at the orphanage. Unfortunately, they are locked away in the mayor's office and Mayor Quantrill won't let anyone see them.

To get the information he wants Dalton will have to return to a way of life he had abandoned long ago and become a thief, an act that risks once again making him a wanted man.
